non-fat milk or water
Non-fat milk is an excellent source of protein, calcium, and B vitamins, with negligible fat content. It is often fortified with vitamins A and D to compensate for fat-soluble vitamin loss during processing.
About
Non-fat milk, also known as skim milk, is milk from which the fat content has been removed through a separation process, typically centrifugation, reducing fat to 0.5% or less by weight. Derived from the lactation of mammals—primarily cattle in commercial production—non-fat milk retains the water-soluble proteins (casein and whey), lactose, and water-soluble vitamins of whole milk while eliminating the fat-soluble components. The resulting liquid is thin in body with a pale, slightly blue-tinted appearance, and has a clean, mildly sweet dairy flavor without the richness associated with whole milk. Non-fat milk serves as a shelf-stable beverage when ultra-pasteurized and dried into powder form.
Culinary Uses
Non-fat milk is widely used in baking, sauces, and beverages where fat content is a nutritional concern or where a lighter texture is desired. It functions as a liquid medium in batters, doughs, and custards, though sauces made with non-fat milk may require a roux or cornstarch slurry to achieve proper body. In coffee and tea, non-fat milk produces less foam than whole milk due to reduced fat. Powdered non-fat milk dissolves readily in both hot and cold liquids, making it valuable for emergency cooking, camping, and recipes requiring long shelf life. It pairs well with grains, cereals, and fortified breakfast applications.
